Trend of Santonian (Late Cretaceous) atmospheric CO_2 and global mean land surface temperature: Evidence from plant fossils

引用

Science China Earth Sciences 2011年第9期54卷 1338-1345页

作者： WAN chuanbiao WANG DeHai zhu ZhanPing QUAN Cheng Exploration and Development Research Institute Daqing Oilfield Company Ltd. Daqing 163712 China College ofGeoseiences Jilin University Changchun 130061 China Key Laboratory for Evolution of Past Life and Environment in Northeast China MOE Jilin University Changchun 130026 China

Quantitative reconstructions of atmospheric CO2 by using terrestrial and marine records are critical for understanding the so-called ＂greenhouse＂ conditions in the Cretaceous, but data from terrestrial plants for several stages of this period remain quite limited. Using the stomatal index （SI） technique, here we estimate the Santonian （Late Cretaceous） CO2 contents based on a sequence of fossil cuticles of Ginkgo adiantoides （Ung.） Heer from three beds of the Yong＇ancun Formation in Jiayin, Heilongjiang Province, northeastern China. By the regress function, Sis of Ginkgo fossils reveal a pronounced CO2 reduction from the early to late Santonian （-661 and -565 ppm, respectively）. The relatively high CO2 levels provide additional evidence for paleoclimatic warmth in this interval. Moreover, available paleobotanical data illustrate a decline trend of CO2 contents throughout the Late Cretaceous, punctuated by several fluctuations in particular episodes with different magnitudes. The CO2 contents shifted notably in the late Cenomanian, Turonian, early Santonian, late Campanian, and probably latest Maastrichtian. Furthermore, a comprehensive study based on CO2 data shows that the global mean land surface temperature （GMLST） fluctuated several times accordingly. The change ratios of GMLST （AT） increased from -3℃ in late Cenomanian to -4.7℃ in mid Turonian, and then dramatically reduced to -2.2℃ in mid Coniacian. From the Santonian onward, it appears that the temperature gradually decreased with a few minor fluctuations.

Age and nature of the Budate Group in the Hailar Basin are of great significance in studying the evolution of the Hailar Basin and the Xing'an-Mongolian Orogenic Belt(XMOB).Zircon U-Pb ages of eight volcanic rocks from the Budate Group and two basement granites in the Hailar Basin were reported in this *** dating results indicated that the formation of these volcanic rocks was consistent with the emplacement of Late Paleozoic basement granite in age(356-290 Ma),i.e.,Early Carboniferous to Early Permian rather than Early *** with regional geology,it was concluded that the Budate Group is the component of the basement of the Hailar Basin,and these volcanic rocks were formed at an active continental margin,which is related to the closure of the Hegen Mountains suture *** captured Neoproterozoic zircons(814-873 Ma) were probably derived from the Neoproterozoic basement materials in the Ergun Block,implying the close genetic relationships between the Ergun Block(including the Hailar Basin) and the Siberian Block.

据50余口钻井揭露,松辽盆地北部隐伏的二叠系自下而上称杜尔伯特组(磨拉石)、一心组(残留海盆)、林甸组(火山弧)和四站组(大湖盆),是海西期阿尔泰型(增生弧型)造山带发育的记录,构造线为北东东向。侏罗系(主体为中侏罗统)大庆群由下部碎屑岩和上部蚀变火山岩组成,是古缝合线活化控制发育的燕山期陆内造山作用的磨拉石建造,构造线仍为北东东向,故侏罗系自内蒙东延入黑龙江省中-西部。晚侏罗世时松辽地区的磨拉石盆地闭合,中-酸性岩浆侵入活动仍十分活跃。据新的同位素年龄、化石和构造线方向等证据将火石岭组、沙河子组和营城组归为早白垩世早期,是北东向构造控制发育的松辽盆地断陷阶段的记录。文章列述了典型钻孔所见二叠系和侏罗系的岩石序列和地层分布,分析了其沉积—构造背景和演化,提出松辽盆地的基底是海西期增生弧型造山带,盆地早期的断陷伸展和火山作用是燕山造山带坍塌的地表反映。在此基础上讨论了早白垩世北东向新生构造在区域构造演化中的意义,探讨了前白垩系的油气远景。

作为预测与健康管理的核心技术,准确的剩余寿命预测对于提高系统的安全性与可靠性具有重要意义。在实际工程应用中,同类产品的不同个体之间通常存在差异,其退化路径并不相同。这就导致通过同类产品历史数据所学习到的模型或参数并不能准确拟合新设备的退化过程。为解决这一问题,基于非线性维纳退化模型提出了一种自适应寿命预测方法。建立同时考虑个体不确定性与测量不确定性的自适应非线性维纳退化模型,并通过卡尔曼滤波、期望最大算法与Rauch-Tung-Striebel平滑减弱维纳过程的马尔科夫性,实现参数的在线更新。通过时间-空间变换推导出对应剩余寿命分布概率密度函数的解析表达式。仿真退化数据与C-MAPSS退化数据集被用于实验验证,实验结果表示,所提出的自适应非线性维纳退化模型能够在线更新模型参数,提高预测精度。
